Recently there has been growing interest among scholars in ethnic retu
rn migration. This article examines return migration during the post W
orld War 2 period of descendants of Estonians who emigrated to Russia
at the end of the nineteenth and at the beginning of the twentieth cen
tury. A case of return migration of West-Siberian Estonians from the O
msk province is used as an example. Structuration theory is adopted an
d return migration is treated as a behavioural norm that evolves, spre
ads and becomes embedded within an ethnic minority living outside its
homeland. The research shows that in the case of West-Siberian Estonia
ns the main carrier of the migration behavioural norm is a generation.
The behavioural norm of Estonians born in the 1910s-1920s has been re
turn migration to Estonia, while the migration behaviour of the 1930s-
1940s and the 1950s-1960s generations can be characterized by urbaniza
tion in West Siberia. Behind these inter-generational differences in m
igration behaviour bn be found the different socialization of the gene
rations, appearing largely on the level of practical consciousness. Th
e results give reason to assume that ethnic return migration over a lo
ng period depends neither directly nor indirectly on momentary environ
mental changes, but rather on changes in people's values, habits, iden
tity etc., which in the case of an ethnic minority living outside its
historical homeland may be followed generation by generation.
